2018-19-31: We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A310 series airplanes. This AD was prompted by a determination that new or more restrictive maintenance requirements and airworthiness limitations are necessary. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
95-12-16: This amendment supersedes priority letter Airworthiness Directive (AD) 95-07-04, which currently requires the following on certain Mooney Aircraft Corporation (Mooney) Model M20R airplanes: repetitively inspecting the exhaust system for cracks, replacing the exhaust system if any cracks are found, and reporting to the Federal Aviation Administration (FAA) any cracks found. This action retains the repetitive inspection requirement of AD 95-07-04 until the exhaust system is modified, and requires eventual modification of the exhaust system on the affected airplanes. Several reports of exhaust system cracks on Mooney Model M20R airplanes prompted this action. The actions specified by this AD are intended to prevent an airplane engine fire that could result from exhaust system cracks.
2008-08-03: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: To prevent electrical malfunction from causing damage to the wiring that may result in arcing or fire, accomplish Pacific Aerospace Service Bulletin PACSB/XL/008. We are issuing this AD to require actions to correct the unsafe condition on these products.
2020-17-02: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 and -8F series airplanes, and Model 787-8, -9, and -10 airplanes. This AD requires removing Kathon FP 1.5 biocide from the fuel tanks and engines, installing a fuel limitation placard, and revising the existing airplane flight manual (AFM) to prohibit operation of the airplane with Kathon FP 1.5 biocide in a fuel tank or engine. This AD was prompted by a report indicating that Kathon FP 1.5 biocide added to fuel and running through the engines can lead to significant engine anomalies. The FAA is issuing this AD to address the unsafe condition on these products.
2005-04-06: The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Model GV-SP series airplanes. This AD requires repetitive inspections of the avionics standard communication bus (ASCB) for any noise interference and repair of the ASCB if noise interference is found. This AD also requires revisions of the airplane flight manual (AFM) to prohibit dispatch of any flight with the integrated standby flight display (SFD) inoperative; to add procedures to facilitate recovery of the cockpit display units in the event that the cockpit displays go blank; and to add flightcrew briefings on the use of standby instruments in case the cockpit display units go blank and do not recover. This AD also requires installing an avionics software update and a hardware upgrade to the Honeywell Primus Epic system to correct a display blanking problem; installing the update will allow removal of certain AFM revisions and will end the repetitive inspections of the ASCB. This AD is promptedby a report indicating that all four cockpit flight panel displays went blank simultaneously. We are issuing this AD to prevent a software error from blanking the cockpit display units, which will result in a reduction of the flightcrew's situational awareness, and possible loss of control of the airplane. We are also issuing this AD to address noise interference in the ASCB, which can interfere with the display recovery after a blanking event and consequently extend the time that the displays remain blank. In addition, we are issuing this AD to ensure that the flightcrew is advised of the procedures necessary to address blank cockpit display units.
94-01-03 R2: This amendment revises an existing airworthiness directive (AD), applicable to Teledyne Continental Motors (TCM) (formerly Bendix) S-20, S-200, S-600, and S-1200 series magnetos, that currently requires replacing Bendix ignition coils and rotating magnets, regardless of total time in service (TIS), with improved TCM ignition coils, rotating magnets and marking magnetos to indicate compliance, except for the S-1200 series magnetos on which the AD requires replacing only the ignition coils as that series magneto already incorporates rotating magnets with the improved TCM design. This amendment removes several notes after the applicability paragraph and inserts these as paragraphs into the applicability itself and into the compliance section to clarify that these actions are mandatory. In addition, this amendment allows installation of replacement serviceable Parts Manufacturer Approval (PMA) parts in addition to TCM parts. Also, this amendment clarifies that Bendix magnetosreplaced with Slick magnetos satisfy the requirements of the AD, and that operators must perform the requirements of the AD on magnetos with Bendix magneto data plates that have been replaced with an overhaul facility's data plate. This amendment is prompted by comments that request clarification of the compliance notes and by the request to install replacement serviceable PMA parts. The actions specified by this AD are intended to prevent magneto failure and subsequent engine failure.
95-11-08: This amendment supersedes airworthiness directive (AD) 73-02-01, applicable to Hartzell Propeller Inc. Models HC-92WK-( ) and HC-92ZK-( ) propellers, that currently requires visual and penetrant inspections of the propeller blade shank area for corrosion at 1,000 hour time in service (TIS) intervals and shotpeening after inspection. This amendment requires a one-time inspection of the blade clamp screws, then a dye penetrant inspection, compressive rolling of the blade shank, and replacement of blade clamp screws, all to be accomplished at intervals of 500 hours TIS. This amendment is prompted by reports of two recent propeller blade separations that occurred at less than 1,000 hours TIS since last inspection. The actions specified by this AD are intended to prevent propeller blade separation, which could result in loss of control of the aircraft.
2008-09-20: We are adopting a new airworthiness directive (AD) for certain Boeing Model 747-200F, 747-300, 747-400, and 747-400D series airplanes. This AD requires a detailed inspection to detect missing fasteners from the shear clip at a certain stub frame to auxiliary sill joint, and applicable related investigative and corrective actions. This AD results from reports of missing fasteners from the shear clip of the stub frame to auxiliary sill joint and cracking of the adjacent exterior skin and internal doubler. We are issuing this AD to ensure that fasteners are installed in the shear clip of the stub frame to auxiliary sill joint. Missing fasteners could result in cracks in the adjacent exterior skin and internal doubler, which can propagate and result in loss of structural integrity and sudden in-flight decompression of the airplane.
2000-17-10 R1: This amendment revises an existing airworthiness directive (AD), applicable to all Lockheed Model L-1011-385 series airplanes, that currently requires modifications of the engine turbine cooling air panel at the flight engineer/second officer's console, pilot's caution and warning light panel on the main instrument panel, and monitoring system for the engine turbine air temperature. That AD was prompted by reports of an undetected fire breaching the high speed gearbox (HSGB) case on certain Rolls Royce engines installed on in-service airplanes due to lack of an internal fire detection system within the HSGB. The actions specified by that AD are intended to prevent undetected fires originating within the HSGB from breaching the HSGB case, which could result in engine damage and increased difficulty in extinguishing a fire. This action removes certain airplanes from the applicability of the existing AD. The incorporation by reference of Lockheed Service Bulletin 093-77-059, dated February 25, 1998; and Lockheed Service Bulletin 093-77-059, Revision 1, dated February 2, 1999, as listed in the regulations, was approved previously by the Director of the Federal Register as of October 6, 2000 (65 FR 53157, September 1, 2000).
2017-06-02: We are adopting a new airworthiness directive (AD) for Fokker Services B.V. Model F28 Mark 0100 airplanes equipped with Rolls-Royce TAY 650-15 engines. This AD was prompted by reports of uncontained engine fan blade failures in Rolls-Royce TAY 650-15 engines. This AD requires installation of a caution placard in the flight compartment. We are issuing this AD to address the unsafe condition on these products.
